Amphibian Declines in the U.S. Have Several Causes

Amphibians have been declining in the U.S. and researchers have been looking into possible causes. Disease, deformities, and habitat loss are taking their toll on frog and toad populations worldwide.

Scientists studying U.S. amphibian populations are finding several factors come together to produce an overall decline. Fewer trees, more algae, pesticide runoff, and other causes are reducing populations. Interestingly, small changes in human behavior could reverse the decline.
